Capture image using the Camera and display it in ImageView, force closes the app. Tried existing answers, doesnt seem to work

Question

For an app, my team is currently working on I want to take a picture with the camera and display that in an ImageView in the same screen.

To do this I tried using an already answered question on Stackoverflow but it doesn't seem to work. I used this one >> Capture Image from Camera and Display in Activity

But whenever I ran the app and click on the ImageView or the button the app force quits. I really have no clue why app is force clossing.

Here is the code that I used in my activity java file:

package com.me.backtrack.backtrack;

import android.app.Activity;
import android.content.Context;
import android.content.Intent;
import android.content.pm.PackageManager;
import android.graphics.Bitmap;
import android.hardware.Camera;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.ImageView;

public class CameraActivity extends AppCompatActivity {
    private static final int CAMERA_REQUEST = 1888;
    private ImageView imageView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_camera);
        this.imageView = (ImageView)this.findViewById(R.id.camera_preview);
        Button photoButton = (Button) this.findViewById(R.id.button_capture);
        photoButton.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
                startActivityForResult(cameraIntent, CAMERA_REQUEST);
            }
        });
    }


    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (requestCode == CAMERA_REQUEST && resultCode == Activity.RESULT_OK) {
            Bitmap photo = (Bitmap) data.getExtras().get("data");
            imageView.setImageBitmap(photo);
        }
    }
}

And the following is my XML layout:

<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.me.backtrack.backtrack.CameraActivity">


    <LinearLayout
        android:layout_width="0dp"
        android:layout_height="587dp"
        android:layout_margin="10dp"
        android:orientation="vertical"
        android:weightSum="10"
        tools:layout_constraintTop_creator="1"
        tools:layout_constraintRight_creator="1"
        android:layout_marginStart="9dp"
        android:layout_marginEnd="9dp"
        app:layout_constraintRight_toRightOf="parent"
        android:layout_marginTop="8dp"
        tools:layout_constraintLeft_creator="1"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        android:layout_marginLeft="9dp"
        android:layout_marginRight="9dp">

        <ImageView
            android:id="@+id/camera_preview"
            android:layout_width="match_parent"
            android:layout_height="0dp"
            android:layout_weight="9"
            android:onClick="onClickCamera"/>

        <Button
            android:id="@+id/button_capture"
            android:layout_width="match_parent"
            android:layout_height="0dp"
            android:layout_weight="1"
            android:text="Capture"
            android:onClick="onClickCapture"/>

    </LinearLayout>

</android.support.constraint.ConstraintLayout>

I am fairly new to android development and I tried many ways to fix this and it doesn't seem like I am doing it the right way.

Please let me know if you need more information

Thanks in advance!
